Calculations for Mirror Symmetry with D-branes

  title={Calculations for Mirror Symmetry with D-branes},
  author={Johannes Walcher},
We study normal functions capturing D-brane superpotentials on several oneand two-parameter Calabi-Yau hypersurfaces and complete intersections in weighted projective space. We calculate in the B-model and interpret the results using mirror symmetry in the large volume regime, albeit without identifying the precise A-model geometry in all cases. We identify new classes of extensions of Picard-Fuchs equations, as well as a novel type of topology changing phase transition involving quantum D… CONTINUE READING
